- Backport #19457 - When 3-way merge is enabled for conflict checking, it has a new interesting behavior that it doesn't return any error when it found a conflict, so we change the condition to not check for the error, but instead check if conflictedfiles is populated, this fixes a issue whereby PR status wasn't correctly on conflicted PR's. - Refactor the mergeable property(which was incorrectly set and lead me this bug) to be more maintainable. - Add a dedicated test for conflicting checking, so it should prevent future issues with this. - Ref: Fix the latest error for https://gitea.com/gitea/go-sdk/pulls/579 Co-authored-by: zeripath <art27@cantab.net>
